Try deleting the package-lock.json and the node_modules folder and do a npm install – Divakar Rajesh

I've encountered this multiple times.

First I would suggest that you run npm uninstall -g create-react-app since the global version isn't supported anymore.

Then try npx create-react-app my-app again.

If that does not work, try to run:

npm init

npm install create-react-app

npx create-react-app my-app

The steps above have solved the issue for me a couple of times

Disconnect and reconnect to your source of internet (WIFI).
After that, run npm cache verify
Next you will want to run: rerun npx create

Working Solution: thanks to idkwhatsgoingon's answer.

create-react-app does not work globally

  1. npm uninstall -g create-react-app
  2. npm install create-react-app
  3. create-react-app app01

try this command first:

npm cache clean --force

and create your react app again.

I got the same error when trying to install netlify-cli. Here are two things I did to solve it:

  1. I deleted some files to clear up disk space
  2. Since my npm version is 6.0+, I ran "sudo npm cache verify"

Add the line

timeout=60000

to your .npmrc config file (create it at ~/.npmrc if it doesn't exist) then run npx create-react-app project-name should be successful. At least it was in my case. (I had code ERR_SOCKET_TIMEOUT before)
